I just finished reading choke
by chuck pahlaniuk, and its a great book. Though I wouldnt say its his best. Its a bit more positive then his usual stuff, but still has his insane and incredible sense of humor and sarcasm.
Also I just finished reading this excellent Frank Miller masterpiece Hard Boiled
, holy shit! When it comes to non stop violence and all out gore, theres nowhere better to look then anything written by Frank Miller. This story though thin is just completely outthere in terms of being ultraviolent to the extreme!
Check it out if your in desperete need to be shocked!
